NetAlertX

NetAlertX is a network monitoring tool that scans networks for devices and reports changes such as new devices, port and IP changes, disconnections, reconnections, and critical devices going down. It provides network visualization and cross-network visibility through the Sync plugin, which synchronizes multiple networks across a range of network device manufacturers.

Features include scheduled and ad-hoc network scans, alerts through more than 80 notification services supported by Apprise (including in-app, email, Telegram, Pushover, NTFY, Pushsafer, and webhooks), and integration with automation platforms to synchronize device status and attributes. Device management can be automated with live presence detection, workflows, and business rules. A plugin system covers monitoring (DHCP servers, Nmap port scanning, NSLookup and Pholus name resolution, website down monitoring, Internet speed test), discovery and import (DHCP leases, Pi-hole, UniFi, other NetAlertX instances), notifications (Apprise proxy, email, webhook, NTFY, Pushsafer, Pushover, MQTT for Home Assistant), and system tasks (CSV backup, database cleanup, DDNS update, log maintenance, and more).

NetAlertX is deployed via Docker, Unraid, and Home Assistant, and is suited to single-site or distributed network management.
